304 [April, 



angulis anticis magnis rotundatis, ante medium transversim impresso, dorso 

 late et profunde sulcato, bicostato, costis integris parallelis, elytris ventricosis 

 postice acutis, pone basin oblique impressis, humeris valde elevatis, crenato- 

 striatis, interstitiis laevibus convexis. Long. -07. 



One specimen found at San Francisco ; the eyes are moderate and prominent, 

 as in tbe next division ; the great elevation of the humeri causes the lateral 

 outline of the elytra to be sinuous anteriorly. It is somewhat related to, but very 

 distinct from L. angusticolis of Europe. 



** Thorax haud carinatus. 

 f Oculi mediocres, convexi prominuli. 



3. L. pulicarius, ferrugineus, elongatus, capite thoraceque fere scabris 

 punctatis, hoc latitudine paulo longiore convexo, lateribus antice rotundatis, 

 postice profunde transversim sulcato modice constricto, elytris nigris, vel nigro- 

 piceis, ovalibus valde marginatis thorace duplo latioribus, confertim seriatim 

 grosse punctatis. Long. -035.

 Corticaria pulicaria Melsheimer, Proc. Acad. Nat. Sc. 2, 115. 

 Middle and Southern States: sometimes very abundant, flying at twilight. 

 Very similar to the European L. lilliputanus. 



4. L. crenatus, niger, capite thoraceque obsolete canaliculars scabris, hoc 

 quadrato postice subangustato, parum convexo, fortius marginato, lateribus fere 

 rectis antice paulo rotundatis, versus basin trifoveato, foveis sulco transver30 

 connexis, elytris ovalibus convexis, thorace duplo latioribus grosse crenato- 

 striatis, interstitiis striis haud latioribus, antennis pedibusque flavis. Long. 

 045. 



Several specimens found at San Jose, California, and one at San Diego. 

 Smaller than the next, with deeper striae on the elytra, and narrower margin. 

 The posterior impression of the thorax is deeper at the sides and in the middle, 

 so that it appears like three foveas transversely connected. 



5. L. reflexus, niger, capite thoraceque scabris canaliculars, boc quad- 

 rato, postice subangustato, parum convexo, fortius marginato, lateribus fere 

 rectis antice rotundatis, postice transversim valde impresso, elytris ovalibus 

 modice convexis, thorace duplo latioribus, valde marginatis profunde crenato- 

 striatis, interstitiis striis latioribus, antennis pedibusque flavis. Long. '055.

6. L. f i 1 i f o r m i s , linearis, depressus, rufo-ferrugineus, occipite coarctato, 

 thorace quadrato-cordato, late marginato, postice modice angustato, impressione 

 transversa po3tica utrinque exarata, elytris thorace vix latioribus dense cre- 

 nato-striatis. Long. .045. 



Dahl, Coleopt. 65, &c, &c. Mann. Germ. Zeitschr. 5, 104. 



A European species, of whieh one specimen was found in Missouri and another 

 at the Academy of Natural Sciences, in Philadelphia. Probably imported in 

 articles of commerce. 



7. L. parviceps, elongatus depressus, ferrugineus, capite thorace duplo 

 angustiore, fronte subtiliter trisulcato, thorace latitudine breviore, lateribus 

 antice rotundatis, postice haud angustato, angulis posticis rectis, valde margi- 

 nato, disco antice trifoveato, postice transversim valde sulcato, elytris medio 

 paulo dilatatis, sexseriatim variolosis, interstitiis perangustis, humeris denticu- 

 latis. Long. -045. 



A very distinct species of which I found but a single specimen, at San Jose, 

 in Calitoraia. The antennae are shorter than in any of the preceding species, 

 being hardly twice as long as the head.
